HARPER F. SMITH, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF FIVE-EIGHTHS TO XVILLIAM F. MCCULLY AND GEORGE MOGOWAN, OF SAME PLACE.

VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 506,560, dated October10, 1893.

` Application filed A fi127. 1892. Serial No.430,359. (No model.)

To all whom it may concern:

Be it known that I, HARPER F. SMITH, a citizen of the United States,residing'in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Vapor-Burners, whichimprovement is fully set forth in the following specification andaccompanying drawings.

- My invention consists of a vapor burner which is provided with a 'coilor coils through which oil or fluid, such as gasoline, is directed andthereby vaporized, said coil or coils being subjected to the heat of theburner, and by their nature producing a large surface for the passage ofthe partially forned and completely generated vapor or gas.

Figure l represents a partial side elevation and partial section of agas burner enbodying my invention. Fig. 2 represents an end Viewthereof. Fig. 3 represents a plan View of a diaphragm employed withinthe burner.

Similar letters of reference indicate correresponding parts in theseveral figures. I

Referring to the drawings: A designates the pipe which is supplied withoil or fluid such as gasoline, from a proper source, as usual in suchcases.

B designates the burner which is screwed or otherwise connected to theclosed end of said pipe. c

C designates a tube, one end of which is connected with a bore D to thepipe A, the same risingfrom said pipe and formed at top into a coil E,and its opposite end enters the burner B at or about the base thereof,after passing within the end of the gas pipe it being seen that saidtube C forms a communication between the pipe A and the burner B. Withinthe burner, above the end of the tube C therein, is a plate or diaphragmF, which has a small orific g therein, of less diameter than the bore ofthe tube C said plate being screwed or otherwise Secured to the closedend of the pipe A, said orifice causing the passage of generated gasfrom said tube C to the burner B.

Connected with the pipe A is a valve H, whereby the supply of fluid tothe tube C may be adjusted or entirely cut off. In the closed end of thepipe A is a valve J, which is adapted to open and close the inlet end ofthe tube O, and nicely adjust the supply of oil or partially generatedvapor thereto, t being evident that while both valves H and J may beenployed, they may be used sepa- 'rately.

The coil E is double, as most clearly shown in Fig. 2, it being noticedthat a coil is formed r at the top of the inlet portion of the tube O,

after which said tube passes to the opposite side as at K, and thenrises having at the top thereof the other coil E, after which itdescends and joins the burner, by which provision the surface of thepipe is vastly increased,it being noticed that the coils are on oppositesides above the burner` and on the sides of the fiame therefrom so as tobe subjected to the heat thereof.

The ends of the tube O respectively lead from and enter the supply pipeA, at or near the center of the top thereof, so as to be n line With thelongitudinal direction thereof.

The operation is as follows: The fluid in the pipe A enters the bore D,where it may be heated by the alcohol cup, shown in dotted lines, th uspartially vaporizing the same, the vapor then passing into the pipe Oand thecoil E, where it is subjected to the intense heat thereof, th usfully Vaporizing the oil and generating a highly volatile gas which isdirected into the burner, at the tip of which it may be consumed, thusproducing a brilliant light and serving to heat the coils E, E, and theadjacent portions of the tube 0. The small orifice G in the plate Fadmits the gas to the burner in a uniform manner, thus causing the lightt-o burn steadily and without flickering.

The burner is provided with openings in the side thereof, whereby airmay be admitted into the same, in order to intermix with the gas andproduce a more perfect-conbustion thereof.

In my burner the fiame isperfeetly white for illuminating purposes. Thereason for having one or both sides of fiattened or doubled coil, isthat the action ot' the heat on the vapor in the coils tends to solighten it that the longer it is exposed to the heat, the better itsquality and brightness. 'In the old construction where there is a tubeon each side in case the wind blows the flame away from one side, the olin that side is not being vaporized, and thus vapor and oil will passthrough together and make the flame junp, where-as in my buruer formedof a single tube, making coils on each side of the burner,the flane isalways in contact with the retort, whchever way the wind may blow.Consequently all of the oil is Vaporized.

It is evident that a torch, &c., may be employed to heat the bore orchanber D and coil E prelininary to vaporization.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is

` l. A gas supply pipe having a bore and a closed end, a bnrnersupported on said pipe, a tube connunicating at one end with said boreand-opening at the other end into said burner, a diaphragm within saidburner having an opening ofless diameter than the opening in the pipeleading into the burner, said tube rising verticallyfrom the supplypipeand having fiattened coils on opposite sides above the top of theburner, said parts being combined substantially as described.

2. A gas supply pipe having a bore in a closed 'end thereof, a valve insaid bore, a burner supported on the closed end of said pipe, and a tubeleading from one end of said bore to above the tip of the burner on oneside 'thei-cof, and then passing below the level of said tip to theopposite side of the burner and entering the burner on the opposite sidetherefrom from the connection of the tube and bore, said tube beingcoiled on opposite sides of said burner, said parts being eonbinedsubstantially as described.

3. A gas supply pipe with a burner supported ther-con at the closed endthereof, and a tube rising from said pipe and communicating with thebore thereof, then having coils on one side of the bur-ner, passed tothe other side thereof, and having coils thei-eat, then descending andhaving its discharge end connected with the burner, said parte beingcombined substantially as described.
